2. RE: docker image cleanup before upgrade

If you're running Resource Manager 6 then it's guaranteed that the old 5.x images are no longer being referenced. Docker images are stored as layers with deltas between them to conserve space. Generally only the most recent version of an image is going to be the one is use with the layers beneath it being old data which can be removed.
